MIL-STD-1399/390, MILITARY STANDARD: INTERFACE STANDARD FOR SHIPBOARD SYSTEMS (SECTION 390) ELECTRIC POWER, DIRECT CURRENT, (OTHER THAN SHIP'S BATTERY) FOR SUBMARINES (02 OCT 1987)., This standard defines the electrical interface requirements for,and the constraints on, the design of submarine systems/equipments whichwill utilize direct current (dc) electric power. This standard does not applyto, nor shall be used for, the design of ship service dc power system loadconnected to the main storage battery. Submarine equipment designers and usersof the system must comply with these interface and systems constraints/requirementswhen developing, producing and acquiring equipments to assure that satisfactoryequipment operation and performance are obtained.【英文标准名称】:Fibre-reinforcedplastics-Methodsofproducingtestplates-Wetcompressionmoulding
